FPM-8220 LabVIEW Instrument Driver Overview
The FPM-8220 LabVIEW Instrument Driver is a collection of Virtual Instruments (VIs) that allow for
remote control of the instrument. These VI's can be used either independently or as building blocks
for a larger, more complex VI. Remote control can be accomplished using VISA sessions over either
of the two communication channels listed below.
USB Communication
The USB connector is located on the rear panel of the instrument. This USB connector is the square
"B"-style connector. A standard USB A/B cable is required.
Configuring the COM Port
With the connected instrument powered on, open National Instruments Measurement &
Automation Explorer and select the port to which the instrument is connected. The correct port
will be listed under My System Devices and Interfaces Serial & Parallel. If the
instrument is connected to a remotely accessed computer, please see the troubleshooting
section of Chapter 3.
When the correct port is highlighted, the Baud rate, Data bits, Parity, Stop bits and Flow control
can be adjusted. From the drop down menu, select the following values:
After the correct values are selected, click Validate and then Save. The COM port is now
configured.
GPIB Communication
The GPIB connector is also located on the rear panel of the instrument. See the FPM-8220 Product
Manual for instructions on setting the GPIB address using the front panel controls.
